WOVEN TAPE OR BAND- Patented April 16, 1907.

Application filed May 23, 1906- Serial No- 318,390.

To 00 whom it may concern.-

Be it known that I, ANDREW WEIMAR, a citizen of the United States,residing in Cheltenham, Pennsylvania, have invented certain Improvementsin Woven Tapes or Bands, of which the following is a specificatlon- '15:" (at:

The object of my invention is to produce a woven band or tape having aclosely-woven center and an ornamental edge with less we penditure ofweft-thread than is usually required in the production of such a tape orband. This object I attain in the manner hereinafter set forth,reference being had to the accompanying drawing, which represents, on anexaggerated, scale apiece of tape or band made in accordance with myinvention and illustrates also the method of weaving the same.

The tape or band shown in the drawing comprises a central strip 1 andopposite edge strips 2, separated some distance from the central strip,but connected thereto by means of the transverse weft-thread 3 which isinterwoven both with the warp-threads of the central strip and withthose of the edge strips, the separation of the latter from the centralvstrip being effected by interposing between the two sets of warp-threadsduring the weaving operation longitudinal bars or templets 4, which areshedded, so as to cause the weft-thread 3 to pass alternately under andover each bar, as shown, the web finally leaving the bars as it is drawnforward by the take-up devices of the loom.

In tapes or bands of this character as heretofore made the central strip1 has been produced by interweaving the weft-thread 3 with warp-threadsin a regular weavethat is to say, one-half of the warp-threads have beenraised, while the alternate threads were depressed to form the shed forthe insertion of the weft-thread, and in order to effect the desiredseparation of the weft-thread shots where they pass from the centralstrip to the selvage strips it has been necessary to interweave theweft-thread with the warpthreads of the central band along for two ormore shots between the successive interweavings of the weft-thread withthe warpthreads of the selvage strips.

In carrying out my invention I avoid the loss of time, labor, andmaterial due to such interweaving of the weft-thread with thewarp-threads of the central strip alone by adopting a cross-weave forthe series of pairs of warp-threads 7 contained in said central strip,these warp-threads being shedded in the same way as the warp-threads 6,which form the selvage strips. The twisting of the warp-threads 7between the successive shots of weft-thread serves to effect the desiredseparation of the latter.

The use of the pairs of cross-warps alone, however, imparts to thecentral strip 1 an open or lace-like appearance, and when it is desiredto produce in said strip a close web I alternate with the pairs ofcross-warps 7 pairs of regularly-shedded warps 8, which thus serve tofill the spaces between the pairs of cross-warps and close the textureof the central strip.

I claim 1. A woven tape or band comprising a central strip and oppositeselvage strips and a weft-thread interwoven with the warpthreadscomprised in each of said strips, said warp-threads being twistedbetween successive shots of the weft-thread to effect separation of thesame.

2. A woven tape or band consisting of a strip comprising a series ofpairs of crosswoven warp-threads alternating with pairs ofevenly-shedded warp-threads, and a weftthread interwoven with thewarp-threads of said strip and forming loops projecting beyond the edgesof the same, the successive shots of the weft-thread being separatedfrom each other by the twisting between them of the cross-wovenwarpthreads.

3. A woventape or band having a central strip and selvage strips spacedapart therefrom, each strip having pairs of cross-woven warp-threads,and the central strip having alternating pairs of evenly-sheddedwarpthreads, and a weft-thread interwoven with the warp-threads of boththe central strip and the selvage strips, the successive shots of saidweft-thread being separated from each other by the twisting of thecrosswoven Warp-threads between them.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ANDREW WEIMAR.
